Describe the steps for simplifying the expression 2x + 3 + 5x – 15.​

Step-by-step explanation:

2x+3+5x-15

I can start off by combining like terms (2x and 5x with 3 and -15)

2x+5x+3-15

and my new equation will be 7x-12. Since they are not like terms (15 does not have x so I can't continue solving), 7x-15 will be my final answer.

Group and add the x coefficients (factoring)

Add the other numbers: 3 and -15

2x + 3 + 5x – 15 = 2x + 5x + 3 – 15 = 7x - 12

Step-by-step explanation:

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
